One screen, five buttons, one ship, a few UFO’s, and several ship-smashing asteroids. You're smack dab in the center of the action with your triangle-shaped spacecraft, adrift in a sea of space rocks. Blasting large, slow-moving asteroids turned them into two medium-sized, speedier asteroids.
The controls allow you to rotate left and right, thrust, warp into hyperspace, and most importantly, to fire your blaster at the rocky menaces.
Special Instructions : Use your mouse to click start, Space bar = Fire , Up arrow key to thrust, Left/Right arrow keys to move left/right.
